Hi On Monday I've got the task of trying to fix a friend's 1GHz Widescreen iMac G4. He lives 200 miles away and I'm making a special journey, so I'd like to arrive as fully clued-up as possible. The machine was running OS X 10.2 Jaguar & working fine, except the SuperDrive, which would refuse to read some DVDs, producing a disturbing clicking noise (reminds me of the old Iomega Zip "Click of Death"). Sometimes if he gave the case a hard slap, it did start working a bit better. However, after attempting to install Tiger, the machine now won't boot. My suspicion is that the SuperDrive failed mid-way through the install process, and has left his machine in an unworkale state. On the phone he's not being very clear about the exact symptoms. He's not that bothered about the SuperDrive not working, but he wants to be able to surf the web and use eMail, use his new iPod Nano (hence his recent attempt to install Tiger), and of course he at least wants his data back. If I can't fix it, he says he's going to buy a cheap (£400) windows laptop from Tesco. So I guess, I've got to first recover his data using target disk mode. Then, I've either got to fix/replace the superdrive, or somehow install Tiger without using the SuperDrive. At my disposal will be my new MBP, a firewire cable, an external USB hard drive, and my wits. Can you buy replacement superdrives for the iMac G4? Can you install Tiger from an external USB drive? Or from an external DVD drive? Any tips? Cheers SL PS: He lives near an Apple store if that's any use.
